<\/a>The same principle is applied for the turbulator, except that it is inserted into the existing convection tube by means of a circular metal rod.<\/p>\n
To quantify the performance of these two solutions, the NGTC tested a two-pass fire tube boiler with a capacity of 175 BHP (5,550 lb\/h of steam produced at 125 psig).<\/p>\n The tests were designed to measure steam production as well as the efficiency and pressure loss at different operating speeds. The tests were performed with:<\/p>\n The results obtained are presented in the following table. Our findings from the tests are as follows:<\/p>\n Efficiency depending on technology used<\/p>\n \n<\/p> \n<\/p> <\/p>\n In the case of a two-pass fire tube boiler of 175 BHP, we can expect approximate costs of $1,000 for the turbulators and $810 in additional costs for corrugated tubes instead of smooth tubes. In the case of a boiler operating at 75% of its rated load, 2,000 hours per year, we can expect a simple return on investment in one month.<\/p>\n For three-pass boilers, a smaller gain in efficiency of around 1% to 3% must be expected, since this type of boiler already performs better. In the case of four-pass boilers, the gains in efficiency are considered negligible.<\/p>\n Thus, for fire tube boilers on which the convection tubes must be changed, the corrugated tube option is quite attractive. If the existing tubes are in good condition, the addition of turbu-lators can be considered. However, in that case, since pressure loss increases considerably, the rated capacity could be affected.<\/p>\n So these solutions are two simple and effective ways of improving the performance of fire tube boilers.<\/p>\n Marc Beauchemin, eng. The Québec market has a great many fire tube boilers, appreciated for their simple construction and affordable cost. A fire tube boiler can be recognized by its cylindrical shape. Inside this cylinder is the firebox, a large-diameter tube in which natural … Lire la suite<\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[405,198],"tags":[590],"yoast_head":"\n\n\n\n\n\n\n\n\n\n\n\n\n\n\t\n<\/a><\/p>\n\n
